About this file
This is a technical specification document for ARFQ DEP25-71, detailing the design and construction requirements for a welded pipe gate system. The specification outlines a comprehensive gate assembly constructed primarily from Schedule 40 steel pipe, featuring an 18-foot overall length with a 2-inch inside diameter main pipe gate and a 6-inch inside diameter installation chamber. The gate design includes specific components such as a lock box assembly, hinge pins constructed from 1.5-inch inside diameter line pipe, grease fittings at each hinge point, and hardened steel reinforcement plates measuring 1/4-inch thickness. The lock box mechanism is engineered to accommodate up to four locks through designated 1/2-inch by 1.5-inch slots, with all pipe ends to be welded closed and the lock box circumference fully welded to the pipe gate. Installation requirements specify that the 6-inch diameter pipe area must be excavated to allow gate placement, then backfilled and compacted after installation.
The specification provides detailed dimensional requirements for all components, including precise measurements for slot dimensions, weld points, and spacing intervals. All steel materials must meet Schedule 40 specifications, and all welded construction must be executed to create a secure, functional gate system suitable for industrial or municipal applications. The document indicates the gate assembly is fabricated using welded construction methodology throughout, with particular attention to hinge durability through dedicated lubrication points. No pricing, funding sources, incumbents, or contract term information is provided in this technical specification document.
